摘要
为了实现煤矿采沉区空间可视化三维演示,解决采沉区复杂的地物分异显示问题,从开源图形软件包OpenGL着手,研究了DEM、影像数据的组织形式,通过对2种数据进行分块处理,导入Oracle数据库进行存储,利用OCI类库以及OpenGL可视化函数实现数据调度以及三维场景的可视化。
In order to realize the 3Dvisualization of the spatial visualization in subsidence area of coal mine,and to solve displaying problem of the complex surface features differentiation in subsidence area,the organization form of DEM and image data was studied by software package of Open Graphics Library(OpenGL).The data were imported to Oracle database and stored in the database by data processing.The data schedule and visualization of 3Dscene were realized by OCI class libraries and OpenGL visualization function.
